ROS commands are not working properly

Probably your ROS_PACKAGE_PATH is not set properly.

You can type in terminal:

 source /opt/ros/<distro>/setup.bash 

If you don't want to run this command on every new shell you open, you have to add this line to your .bashrc file:

echo "source /opt/ros/<distro>/setup.bash" >> ~/.bashrc
source ~/.bashrc
